The Martyr CM832598A is a direct-fit aluminum replacement transom plate anode for Volvo Penta 280 and 290 series sterndrives.

Parts Desk Insights
Best use case: The CM832598A aluminum anode is the most versatile choice for Volvo Penta 280/290 owners who operate in mixed or variable water conditions, or who want a single anode type that performs reliably across both fresh and salt water. It’s also the correct choice for customers who want to match the full aluminum kit (CM280KITA) for consistent alloy protection across the entire drive.
Common customer questions: Customers often ask whether they need to replace all anodes at once — the answer is yes when possible, as mixing alloys (e.g., zinc and aluminum on the same drive) can reduce overall protection effectiveness. If a customer’s anode is depleting in less than a season, a stray current or bonding issue is the likely cause rather than an undersized anode.
